vSphere 7.0 Update 2a was just released yesterday and it introduces the highly anticipated vSphere Virtual Machine Service which is part of the vSphere with Tanzu solution. Customers will now be able to get the exact same Kubernetes-native provisioning and management experience for deploying Virtual Machine based workloads along side their Kubernetes-based applications.
I was definitely interested in checking out this new feature and quickly navigated to my VCSA to start the upgrade and to my surprise, I noticed that both the Stage Only and Stage and Install buttons were disabled (grayed out) and preventing me from updating to the latest release!
I had filed an issue internally and after some troubleshooting, it looks like this may have been remnants caused by the previous Exception occurred in install precheck phase issue, which I had ran into during the update to 7.0 Update 2. Although I was initially pointed by Engineering to VMware KB 83145, it did not resolve the issue and I ran into a couple more errors like "Previous patching unsuccessful" and "Downloading RPM …." messages within the VAMI UI as shown in the screenshots below
